Does the first row have to be headers?

Yes, the first row provides the key names for every object.

How are commas inside values handled?

Values wrapped in double quotes keep their commas and stay in one column.

Can I paste directly from Excel?

Excel copies tab-separated text; save as CSV first or use a TSV-to-CSV tool.

Are numbers converted?

Values are kept as text so nothing is changed unexpectedly, such as leading zeros in IDs.

What about empty cells?

They become empty strings in the JSON.

No, conversion happens in your browser.

What the CSV to JSON Converter does

Convert a CSV file or pasted spreadsheet data into JSON. The first row is used as field names, and each following row becomes one object in a JSON array.

It's the quick way to move data from Excel or Google Sheets into an app, API or script.

Why the CSV to JSON Converter is useful

Spreadsheets are where data gets collected, but code and APIs usually expect JSON. Doing the conversion by hand invites mistakes.

Quoted values containing commas, like "Lahore, Pakistan", are handled correctly so columns don't shift.
